Membrane Water Wall Tubes With Fin Bar For Boiler&Heat Exchanger
Product Introduction: Boiler Membrane Water Wall Panel
Water wall when the original design, the purpose is not heated, but to the cooling chamber of a stove or furnace is not affected by high temperature damage later, due to its good heat exchange function, gradually replace the drum become main heating boiler parts laying on the inner wall of the furnace is made up of many parallel tube evaporative heating surface water wall's role is to absorb or flue gas heat radiation, high temperature flame in furnace in the tube to produce steam or hot water, and decrease the temperature of furnace wall, furnace wall in large capacity boiler furnace flame temperature is very high, the intensity of heat radiation in large boiler 40 ~ 50% or more of the heat absorbed by the water wallWith the exception of a few small capacity boilers, modern water tube boilers all use water wall as the main evaporative heating surface
1. Membrane walls are widely used in boilers for utility/power stations as a heat exchange part.
2. Membane water wall panels were combined with steel tubes and flats to ensure a good sealing and significant reduce the air leakage factor of negative preasure boiler,improve combustion condition in furnace.
3. Membrane water wall panels increase radiation heat surface and save steel consumption.
Advantages
1 | To guarantee the leakproofness of furnace wall and reduce the air leak of combustion chamber. |
2 | To achieve the full water cooling of combustion chamber, and the boiler accessories membrane water wall is benefit to prevent coking under the condition of supplemental firing. |
3 | The thermal storage capacity is small, the warming of combustion chamber is fast and the cooling is also fast, which could shorten the cooling time of boiler’s start and furnace shut down. |
4 | It is good to adopt top supported water cooled wall and it could reduce the load of boiler framework, which is benefit to overhang. |
5 | Compared with the bare tubes, the membrane water wall improves the heat absorption capacity of tubes. |
6 | The factory direct boiler membrane water wall could improve the Preliminary combination degree of boiler parts and reduce the installation workload. |
Manufacture
HD Boiler use submerged-arc welding technology to produce water walls as Eco-friendly requirement.
It also can guarantee a good sturdy construction and sealing.
Features
1. Sturdy construction
2. High strength
3. Accurate dimensions
4. Corrosion resistant finish
